    I had the same problem in one of my trucks today, swapped the controller solenoid but not the iso mod.

    Did u hook up the little red wire that comes out of the control harness to a good 12 v ignition source? You should also check the fuses by the isolation module. Next verify that the ground interconnect is plugged in. This is a pair of black wires with orange stripes. They can be found next to the isolation module too. They have a male and female black plastic quick connector. If this is not connected the plow won't work. And finally verify that your small wires are connected properly at the motor relay ( you guys call it solenoid) there r two wires with small loops that go to the small lugs for the magnetic coil. Then there is one wire with a big loop. This one MUST go to the big lug that is hot all the time. People often put it on the output side of the relay in which case it does not get power to feed those two fuses by the isolation module.
